  1. APX Environmental Registries Ashley HoustonMarket Development Manager, APX508.650.2045 ahouston@apx.com Western Governors’ Association - Renewable Energy Tracking and Certificates Scoping Meeting Salt Lake City, UT April 25, 2003

  2. APX Environmental Registries • Centralized registries that track generation attributes and title • Based on concept of unbundling - environmental attributes of electric power are separated from the energy commodity • Registry databases assists all participants to comply with: • RPS and GPS requirements • Disclosure regulations • Product verification • Other purchase requirements

  3. Registry System Examples • Texas Renewable Energy Credit Program • APX delivered Texas RECs system to ERCOT • monitors RPS compliance and computes RPS • Deals with renewables only, no emissions • www.texasrenewables.com • NEPOOL Generation Information System • APX is administrator of the NEPOOL GIS • Registry tracks RPS eligibility, generation attributes, and emissions factors from ALL generation in the ISO-NE control area including imports and exports • www.nepoolgis.com

  4. NEPOOL ERCOT Compared

  5. NEPOOL GIS Principles • Flexible design to accommodate each state’s unique legislation • Certificate based, all MWhs tracked • Web-based account management • Follow NEPOOL Information Policy with respect to confidential information • Track and document certificate transfers within and between all accounts • Account types - generator, LSE, regulator, trader

  6. NEPOOL GIS Overview • Supports various RPS, GPS and disclosure reporting requirements in the six New England states • Accounts for all generation in ISO-NE from source to sink • Authenticates generation attributes and creates base for verifiable tradable certificate markets • One certificate created for each MWh of generation; one obligation created for each MWh of load served; LSEs acquire certificates to match obligations • Certificates contain 42 data fields - emissions, fuel source, RPS eligibility, serial number etc. • Automates complicated processes (reserve transactions,pumped storage, imports/exports, “residual mix”, line losses, etc.)

  7. Using Certificates to Meet Requirements

  8. Stakeholder Process and Lessons Learned

  9. Stakeholder Participation • GIS Advisory Committee • NEPOOL committee formed to explore a system to support regulatory requirements - includes regulators, generators, LSEs, environmental advocates, NEPOOL counsel, APX as Administrator, ISO New England staff • Tasks include: • Functional Requirements and RFP development • Bid review and contractor selection • Contract negotiation • Operating rules development • Semi-annual operating rule updates

  10. Issues Addressed • Creation and Assignment of Certificates - certificate fields, sources of data, initial assignment, imports, account holders • Transfer of certificates - trading periods, residual mix, retirement, tag transactions • LSE Obligations - calculation of obligations, allocation of residual mix • Reports and Information - account holder, regulator, public and market surveillance reports; confidential information

  11. Key Issues • Treatment of imports/exports and regional compatibility • Trading/settlement periods • Treatment of QFs • Small and BTM generation • Reserved certificates

  12. Three Perspectives • Policy - certificate systems are developed in large part to provide verification for regulatory compliance, therefore should be designed to support public policy and offer the precision, accuracy and transparency needed to satisfy regulators and back-up financial transactions • Market - certificates systems can facilitate the development of new renewables generation and can help spur retail markets, therefore should be designed to provide maximum flexibility and liquidity. • System Compatibility - certificates systems can lead to additional seams issues, therefore should be designed to reduce, eliminate or avoid seams between control areas.

  13. As a result... • Negotiation, compromise needed between these sometimes competing interests/goals • Cannot create systems in a vacuum - dialogue needed between control areas/states • Regulators need to be extremely clear on what they are looking for - otherwise process gets bogged down; regulator caucus developed in NE • Need regulatory participation and buy-in to process

  14. Other Lessons • Once there was agreement on what kind of system to implement, the process went fairly smoothly and quickly - hinged on: • regulatory participation, input, and support • ISO New England participation, input, and support • However, contentious issues hotly debated • Semi-annual operating rule change has been effective in addressing issues - ability to make adjustments once system up and running has been key to success
